CHILTON - Instead of calling 911 when a man they knew began overdosing, three people drove him to another residence, where a fourth person summoned his mother, according to court documents filed this week.

She arrived and told them to call 911.

The four were charged in Calumet County court this week in connection with the ultimately fatal April 2015 overdose of 39-year-old Jeremy Pate-Hilton. An autopsy showed his death was caused by cocaine and fentanyl, an extremely powerful opioid.

Richard "Ricky" J. Partridge, 31, of Chilton, was charged with being party to the crime of second-degree recklessly endangering safety, theft from a person or corpse, possession of cocaine and obstructing an officer.

Matthew J. Lampereur, 31, and Stephanie L. Lampereur, 27, both of Hilbert, were charged with being party to the crime of second-degree recklessly endangering safety.

Richard M. Partridge, 58, of Chilton, — the father of Ricky Partridge — was charged with obstructing.

The younger Partridge "admitted that if they would have called 911, they could have saved Jeremy's life," the complaint states. A doctor agreed.

According to the criminal complaint:

Officers were called to Richard M. Partridge's home on the afternoon of April 30, 2015, for a medical call involving Pate-Hilton. Over the course of interviews, officers learned that Pate-Hilton had not, in fact, fallen asleep on the couch and not awakened, as the Partridges first said.

Instead, Pate-Hilton was with Ricky Partridge at the Hilbert home of Matthew Lampereur and Stephanie Lampereur, where Ricky Partridge said he had stopped to pick up marijuana. Drugs were used when they arrived there, and Matthew Lampereur said that Pate-Hilton also smoked his crack pipe.

Pate-Hilton started overdosing and CPR was unsuccessful. Ricky Partridge told police his mind raced, he thought about calling 911 but told himself he couldn't because he was at his marijuana dealer's house. He said Matthew Lampereur and Stephanie Lampereur also told him he couldn't call 911 because this was happening at their house. Matthew Lampereur told police that he thought about calling 911 but Ricky Partridge told him he couldn't.

The three instead drove him to Richard M. Partridge's home in Chilton. Matthew Lampereur said when they arrived, Ricky Partridge took money and a cigarette pack with crack cocaine inside out of Pate-Hilton's pocket and put it in his car.

Richard M. Partridge called Pate-Hilton's mother, who came over and told them to call 911.
